Oh you got it wrong ev training is training the stat not the stat itself.

For every 4 ev you train, it equates to 1 stat point. So 252/4 is 63 stat points (at level 100) higher than without any ev investment.

The reason why you don’t just max at 255 ev for a stat is because those extra 3 ev are useless since it won’t round up. Now the maximum amount of ev a Pokémon can have altogether is 510. (Extra 2 ev are useless). In competitive battling, you would usually want 252 ev in the Pokémon’s 2 best stats and 4 more ev into 3rd best (or whatever is needed). This isn’t always the case because sometimes you just need to outspeed a specific speed tier or have just enough bulk to survive a specific hit. Having those 4 extra ev at the end isn’t possible if you completely max out the ev. You don’t want any to go to waste.

To put it simply, the value you see on the Pokémon’s summary page on stats is different to ev training. Ev training, iv breeding, natures and base stat are the factors that change your final stat distribution you see on the summary page.

If you want to learn more about how these stats works, use Bulbapedia. It’s a bit hard to explain and it can be very confusing since there are so many variables that can affect how stats work. Search up Bulbapedia stats and you should find what you need.
